At present, many of the small and medium-sized enterprises are still using the low-end singlechip to develop products, the completed function is limited and the code is not portability. A new development scheme is transplanting embedded operating system into specific microprocessor to accomplish more powerful functions. μC/OS-II, as a kind of open source code and small real-time operating system,...
Nowadays, embedded system is one of most popular and promising fields of IT applications, and embedded technology will be more extensive development. ARM processor becomes a mainstream processor in the embedded system because of the characteristics of high cost and low power cost. A video acquisition system using ARMS3C2440 microprocessor is designed, and the entire functional module based on V4L...
Embedded system has more and more applications today. Introduced embedded operating system in embedded system has been a tendency of Embedded system development. Embedded operating system can avoid different embedded system hardware's difference, it can greatly reduce the development costs, shorten the research cycle, μ C/OS-II is a kind of excellent embedded operating system which is an open source,...
To lower the risk in developing a TCP/IP Off load Embedded System (TOES), one may rely on certain platform containing a single or plurality of embedded microprocessor(s). However, previous work shows that it is not easy to use such a slow-clocked microprocessor(s) to achieve high speed goal. Hence this work proposed an efficient architecture of a TOESas well as buffering processes which guarantee...
Sensor network is an important technology in the domain of information technology application. Based on the embedded system and the transmission network bus, this paper offers the system structure and the testing flow of an evaluation system for the design structure of sensor network. The software and hardware of the evaluation system could be modulated based on user's requirement. The structure and...
One of the most frequently used operations in image recognition is morphological processing. In this paper, we propose a parallel implementation of morphological processing optimized for Cell Broadband Engine (Cell), which is one of the latest high performance embedded processors. By utilizing the computational power of Cell suitable for image recognition, we achieve high-speed morphological processing...
Cell Broadband Enginetrade is a multi-core system on a chip and is composed of a general-purpose power processing element (PPE) and eight synergistic processing elements (SPEs). Its high computational performance is achieved mainly through the SPE's processing power. New high-speed NICs such as 10-Gbps Ethernet require significant amounts of processing power. Even the full processing power of PPE...
